Answers to 3 Common Questions about Capsule Filling

Because of better equipment and better understanding of the filling process, Today’s capsule filling machines produce as many as 200, 000 capsules per hour. For some who are new to the capsule filling, you probably have some basic questions about the operation. Now this article KOS provides will give you some answers to common questions about capsule filling.

  1. How to determine the appropriate capsule sizeof your formulation?

First you need to determine the density of the formulation to answer this question. For powder formulations, use the tapped density value. For pellets or granules, use the bulk density. Once you have this information, you will know the target fill weight. If you don’t know the information, ask a reliable supplier to help you analyze the density of the formulation. KOS machinery has a professional customer service center to help you whatever you ask.

  1. How to ensure capsule filling quality?

The traditional approach is to perform a quality check on a small sample (usually 10 capsules) every 30 or 60 minutes when you take a weight-check sample. Although it is a good way to observe the capsule filling quality, but visual inspect is necessary, which inspecting the batches to remove defects that were not always found in the routine quality checks. Most important thing is that you need to record the problem and solve problems after finding failure. Once you have a large scale of data, you will easily conclude main elements to the failure and then adjust it. If you can’t solve problems about the defect capsule filling, you need to tell us immediately. We Kos will supply a troubleshooting guide to assist with you in analyze your situation.

  1. Where and how should store capsules?

To avoid exposing the capsules to high temperatures or to cycles of high and low temperatures, it’s important that this moisture content is maintained. Maintain the area where you store the capsules at 15° to 25°C and 35 to 55 percent relative humidity (RH). Do not store empty capsules in freezers. The empty capsules are also very susceptible to damage because the capsule walls are unsupported.

Warehouse storage areas should be temperature-mapped and monitored to ensure the room temperature is under control and that product-specific refrigeration/RH requirements are maintained. Ideally, the storage area would be equipped with alarms and there would be product-specific product handling procedures that explain how to deal with out-of-limit temperature/humidity incidents. Protect the capsules from direct sunlight by storing those away from windows and skylights. They should also be stored away from radiators, heat registers, hot water pipes, and steam pipes. Keep the capsules out from under potential sources of water condensation, such as water pipes, and keep pallet loads off the floor.

If you understand above points, you can easily ensure capsules filling quality. Kos is specialized in filling machines including manual filling machine, vital filling machine and capsule filling machines for many years. If interested, please visit our websites:
